摘　　要：通过对遭受氯盐腐蚀的某大型商场框架柱进行检测及加固,探讨了氯盐腐蚀机理,提出了三种加固方案,并对加固方案进行了对比。采用化学灌浆和加大截面综合法对该框架柱进行了加固。加固结果表明,该工程在加固14年后仍能安全使用,加固效果良好,可以针对此类工程推广应用。Detection and reinforcement of a large stores framework deteriorated by chlorides induced corrosion,discusses the corrosion mechanism of chlorine,putting forward three kinds of reinforcing schemes,and the reinforcing schemes are compared.Using chemical grouting and enlarging section of the synthesis of framework reinforced.The practical running shows a good effect,results showed that the engineering reinforcement in 14 years,still can use safety.This method can be applied to the similar projects.
